Name three types of rocks.

Answer :

Igneous, sedimentary and metamorphic rocks are the three types of rocks.


(i) Igneous Rocks: These rocks are formed when magma (molten rock deep within the earth) cools and hardens.


(ii) Sedimentary Rocks: These rocks are formed from particles of sand, shells, pebbles, and other fragments of material.


(iii) Metamorphic Rocks: Metamorphic rocks are formed under the surface of the earth due to the changes from increased pressure and temperature.
